Calculation of eddy currents in moving structures using a finite element method on non‐matching grids

F. Rapetti, L. Santandrea, F. Bouillault, A. Razek

This paper deals with the numerical simulation of eddy current distributions in non‐stationary geometries with sliding interfaces. We study a system composed of two solid parts: a…

Hybrid deterministic/stochastic fuzzy methods for the optimization of electromagnetic devices

P. Alotto, P. Girdinio, G. Molinari, M. Nervi

Discusses the combined use of a modified version of the global optimization technique simulated annealing and a deterministic optimizer based on Shor’s method. Describes the…

Adaptive FEM in 3D non‐linear magnetostatics

P. Alotto, A. Castagnini, P. Girdinio, M. Nervi

An adaptive FEM for 3D magnetostatic problems involving non‐linear materials and permanent magnets is presented. The problems are formulated in terms of scalar potentials and…

AR‐modelling bispectrum estimation – A comparison of existing methods and new contributions

Antolino Gallego, Diego P. Ruiz

This paper deals with bispectrum estimation via autoregressive (AR) modelling of a process contaminated by additive Gaussian noise (white and coloured). Two main contributions are…

Magnetic permeance of doubly‐salient airgap geometry with finite slot depth and tapered teeth

Jawad Faiz, John W. Finch

Method of unaligned permeance determination for a doubly‐salient rectilinear airgap with infinite slot depth is used in order to cover a wider range of gap geometry. The results…

Boundary‐integral approach to determine the magnetic field created by a permanent magnet put in free space

Krystyn Pawluk, Zdzislaw Życki

Magnetic field analysis of a permanent magnet put in free space can be effectively performed by a boundary‐integral technique completed with an iterative procedure following a…

Effect of slot depth on the permeance of aligned teeth in a doubly‐salient rectilinear toothed structure

Jawad Faiz, John W. Finch

Effect of slot depth on the evaluation of permeance in the aligned position for identically slotted rectilinear tooth geometry can be carried out using conformal transformations…

An adaptive mixed formulation for 3D magnetostatics

P. Alotto, I. Perugia

An enhanced version of a mixed field‐based formulation for magnetostatics previously developed by the authors is presented and its features are discussed. The formulation…
